The affordable
Premium lightweight
timber framed floor
system that feels like
a concrete floor.
TECSLAB™ is designed for
low, medium and highdensity construction and
combines the properties of
two exceptional construction
products TECBEAM™ and Hebel®
PowerFloor™ to provide a
superior floor solution achieving
quicker build times and
significant cost savings.
Hebel® is a lightweight steel-reinforced Autoclaved
Aerated Concrete (AAC) that has been used in Europe
for over 70 years and here in Australia for over 20
years.
TECBEAM™ is a composite structural ‘I’-Beam which
has a continuous galvanized steel web and timber
flanges resulting in a lightweight beam with structural
properties closely resembling those of a steel beam
rather than a solid beam. TECBEAM™ is designed and
manufactured in Australia by licensed fabricators and
holds worldwide patents for its technology.
Introduction
SLAB
A high-performance lightweight
flooring system
TECSLAB™ is a high performance lightweight flooring
system which provides a superior floor solution, with
the qualities and feel of a concrete floor and the
rigidity of a steel frame, at a significantly reduced cost.
TECSLAB™ can be easily installed by on-site carpenters
and is unaffected by wet or changing weather during
installation. Unlike wet-pour concrete, TECSLAB™ is
installed without the need for curing or propping.
Supremely comfortable, solid
and low noise emitting
The TECSLAB™ system reduces foot-fall, airborne noise
between floors and eliminates squeaking that is often
a problem with other joist systems and particle board
flooring.
TECSLAB™ boasts superior thermal performance
(particularly for suspended floors) and assists in
achieving thermal ratings that reduce heating and
cooling costs.
Proven in the market and
Australian designed and made
All components of the TECSLAB™ system are 100%
manufactured in Australia. Hebel® is manufactured
by CSR Building Products Limited and TECBEAM™
is fabricated by licensed Australian fabricators. You
can depend and rely on the product quality, technical
expertise, warranty and continuity of stock supplies.
With TECSLAB™ you can trust that everything has
been proven and tested*. The components are being
continually improved with ongoing research and
development.

TECSLAB™. Better to build with…
Lightweight yet
solid and tough.
The TECSLAB™ system is
comprised of composite joists
made from timber flanges
and galvanized steel webbed
TECBEAM™s, which are typically
spaced at 450 or 600 centres;
together with the Hebel®
PowerFloor™ – a 75mm thick, steel
reinforced building panel made
from AAC (Autoclaved Aerated
Concrete) supplied in a length
1800mm by 600mm wide with a
tongue and groove profile.
Faster construction period
TECSLAB™ is a timber frame solution and is faster to
construct than suspended concrete. No propping and
curing of concrete is required. Typical placement rates
of 70m2 per day can be achieved with follow on trades
starting after 24 hours.
The TECBEAM™s can be installed quickly due to their
bespoke, made to measure fabrication. On site installation
time is accelerated as minimal modifications to the product
need to be made in-situ.
A comforting thought for a
comfortable living environment
Hebel®’s unique AAC construction provides superior
insulation qualities for a masonry product. The unique
combination of thermal resistance along with thermal
mass, make building with Hebel® a smart choice for
meeting Australia’s stringent building regulations.
For unit and home owners, the thermal efficiencies of
Hebel® reduce the reliance on heating and cooling
appliances – the combined effects of using a heater less
in winter and fans or air conditioning less in summer and
warmer months can have a big impact on rising energy
costs.
Highly fire resistant for peace of mind and added security
Hebel® is non-combustible and renowned for its highly fire
resistant properties. The PowerFloor™ System achieves a
FRL (Fire Resistance Levels tested at CSIRO) from 60–90
minutes below (with relevant fire-rated CSR Gyprock
ceiling) and –/240/240 minutes from above.
A sound reason for
better acoustic qualities
TECSLAB™ answers the practical issue of sound transfer
between floors. Creaking timber is a thing of the past as
the tongue and groove solid concrete floor locks together
and is reinforced with the rigidity of the TECBEAM™.
TECSLAB™ provides superior airborne noise insulation
particularly good for foot fall noise when installed with
resilient mounts. With home theatres becoming standard
in many modern homes, you can enjoy your entertainment
without disturbing the rest of the family.

Introduction
Hebel® PowerFloor™ panel
TECBEAM™ joist
Strongback
Wedges
Sustainability for a better world
in the long term starts today
TECBEAM™ achieves long spans and point load
carrying capacity whilst using far less steel than
standard structural steel bearers and joists. TECBEAM™
joists contain less that 15% of the embodied energy
of the steel beams they replace, without reducing
structural performance. TECBEAM™ provides an ideal
sub-structure for Hebel® due to its stiffness and low
long-term creep and deflection properties.
Hebel® delivers a diverse number of environmental
benefits over particle board and concrete. In an
independent Life Cycle Assessment (the leading
methodology used to quantify the environmental
impacts of a product’s entire life) undertaken by
Good Environment Choice Australia, in accord with
international standard ISO 14 024, Hebel® was found
to have clear environmental benefits across all key
environmental criteria.
To be awarded the label, products must have a 30%
lower impact than alternatives. Hebel® uses 64%
and 43% less greenhouse gas emissions than the
comparative products, concrete and particle board
flooring.
As environmental consciousness and social
responsibility increases, TECSLAB™ is striving to exceed
further to set new sustainability standards in building
materials and residential living.
...for all the
best reasons
With the attributes and benefits shown above this
innovative and versatile composite system provides
confidence that TECSLAB™ is an ideal solid floors
solution, as is detailed throughout the remainder of
this Design and Installation Guide.Less problems with
site access and disruption
Eliminates headaches of concrete truck queues and
pumps on site.
Better Environmental Choice
Environmental studies have demonstrated the
TECSLAB™ system replacing a suspended concrete slab
results in greater than 75% reduction in embodied
energy for an entire floor system. TECBEAM™ joists
contain less than 15% of the embodied energy* of the
steel beams they replace without reducing structural or
other environmental performance. Hebel® is certified by
Good Environmental Choice Australia.

Further information on floor/ceiling systems is available
through CSR Gyprock, or the publications, CSR Gyprock
Fibre Cement Fire & Acoustic Design Guide (‘The
Red Book™’), NºGYP500, and CSR Gyprock Ceiling
Systems Installation Guide, NºGYP570 and TECBEAM™
Installation Guidelines.
Timber & Steel Support Systems
Caulking
TECBEAM flooring can be used to support the Hebel
PowerFloor™ panels. The allowable spacing of the
joists is 450mm or 600mm only. The joists, bearers
and other supports shall be sized in accordance with
the framing manufacturer’s recommendations. Where
steel joist framing is used it must be ensured that the
PowerFloor panels are provided with uniform and
complete bearing onto each steel joist.
Hebel® PowerFloor™ requires that all gaps at
openings, penetrations and control joints be caulked
to provide an airtight floor system that maintains
acoustic, thermal,vermin and fire resistance
performance. All gaps must be carefully and completely
filled with an appropriate flexible polyurethane sealant,
installed in accordance with the sealant manufacturer’s
specifications.
Note: The designer should allow at least 51kg/m2 for the
selfweight of the Hebel® PowerFloor™ panel. A minimum
joist flange width of 45mm is required.
Hebel® Patch
™
®
Hebel Adhesive
®
Hebel® Adhesive (supplied in 20kg bags) is used for
gluing the panels together at all joints. Typically, panel
joints are 2-3mm thick. Sufficient pressure is to be
applied to the joint to ensure full coverage of adhesive
in the joint. Adhesive is to be mixed to the proportions
as stated on the bag.
Construction Adhesive
A 5mm (minimum) bead of Fuller Max Bond
construction adhesive is applied to the top of the joists.
Minor chips or damage to panels are to be repaired
using Hebel® Patch. Hebel® Patch is available in 10kg
bags.
Hebel® anticorrosion
protection paint
Reinforcement exposed when
panels are cut shall be coated
with a liberal application
of Hebel® anti-corrosion
protection paint.

1.4 Design Considerations
Acoustics
• Typically at a max. spacing of 6000mm.
Placement of insulation in the ceiling cavity can enhance
the sound insulation performance of a floor/ceiling system.
A carpet/underlay floor covering incorporated with
TECSLAB™ will provide the best impact sound resistance.
For hard surface floor coverings, we suggest using a
floating floor and/or an independent ceiling system,
incorporating resilient mounts or resilient furring channels.
• Over lines of support for the TECBEAM™ joists. Refer to
Fig 3.10.
For ceilings that incorporate resilient mounts or resilient
furring channels, flanking sound paths through adjacent
walls are common, especially in timber framed buildings.
To maintain Rw and IIC ratings, the wall linings may also
need to be resiliently mounted. For multi-tenancy buildings,
providing a control joint at the party wall will break a
flanking path and maintain acoustic amenity.
Alternative Framing
TECBEAM™ joists may be used without reducing the
system FRL rating for a fire source ‘from above’. The design
of joists shall allow for temperature effects. Alternative
support framing systems may affect acoustic performance,
and advice from an acoustic consultant is recommended.
Penetration Restrictions
Penetrations are required to accommodate services, such
as waste pipe-work, water pipe-work, and air conditioning
ductwork, etc. Hebel® PowerFloor™ can accommodate an
80mm maximum circular penetration without a reduction
in structural performance. Multiple penetrations in the
same panel are to be in a straight line, parallel to the long
edge of the panel.
For large or clustered multiple penetrations, additional joists
or bridging should be included for support of the panel
in this area. Refer to the ‘Penetration & Notching Details’
section of this guide. All penetrations are a potential source
for water ingress or air leaks, and should be sealed with an
appropriate flexible fire rated sealant or proprietary collar.
Control Joint Layout
Control joints are a necessary part of Hebel®
PowerFloor™. Control joints provide a region in which to
relieve stress due to movement of the structural system,
and to control the location where movement can occur
without a detrimental effect on the floor finish.
Recommended locations for control joints are:
10
• Located at lines of bracing, ensuring a diaphragm
between the bracing lines
• Located at changes in joist orientation.
Wet Area Floor Construction
All wet areas require a waterproof membrane layer
over the Hebel® PowerFloor™ panel. Waterproofing
membranes shall be nominated by the designer or
specifier, and installed in accordance with manufacturer’s
recommendations.
Serviceability Behaviour
The deflection limits of the floor are governed by the
adopted TECBEAM™ size. As a guide, the following typical
deflection limits provide acceptable behaviour and dynamic
response:
• Dead Load (DL): span/300 or 12.5mm max.
• Live Load (LL): span/360 or 9mm max.
• DL & LL: span/400.
• Dynamic Response: 2mm max. under a 1kN point load.
Concentrated Loads
For concentrated loadings, such as a loadbearing wall or
point loads, the designer should ensure additional joists or
blocking are provided beneath the wall or bearing plate.
This will reduce the localised bearing stress. Bearing stress
in the AAC shall be limited to 1.0MPa.
Note: The designer should select appropriate deflection
limits to suit individual projects.
Bracing Walls
For bracing walls parallel to TECBEAM™ joists, a joist
shall be positioned beneath the wall. For bracing walls
perpendicular to TECBEAM™, blocking shall be positioned
beneath the wall. Blocking shall have a minimum width
of 45mm. Bearing stress in the AAC shall be limited to
1.0MPa.
Panel Support
All Hebel® PowerFloor™ panels are to start and finish on a
TECBEAM™. Panels must be joined on a TECBEAM™.
This specification should be adopted as a guide only,
and shall be superseded by the contract specifications
of the project.
Please note * denotes areas to insert or select
appropriate specifications.

2.1 System Properties
Structural Performance
Acoustic Considerations
TECSLAB™ systems can support a maximum uniformly
distributed load of 5kPa, or concentrated (point) load
of 1.8kN over a load area of 350mm2 (with joists at
450mm or 600mm centres only) 3.9kN over a load area of
10,000mm2. For loads outside this range, please contact
CSR Hebel® or your TECBEAM™ fabricator.
Sound Ratings
The designer should specify the magnitude of the gaps
between the Hebel® PowerFloor™ panel and structure. This
gap will allow movement to release any confining stresses
due to movement of the supporting structure.
Durability
Where TECSLAB™ is installed in a multi-residential/
commercial application, the PowerFloor panels must be
suitably protected against trafficability during construction
to maintain the long term durability and integrity of the
panels. It is the responsibility of the builder to provide
and maintain such protective coverings to the PowerFloor
panels until such time that the finished floor coverings are
installed.
For application of TECSLAB™ in commercial projects Hebel®
Technical Services must be contacted for advising on
durability and protection of the PowerFloor panels during
construction.
Fire Resistant Levels
Australian building regulations express the fire
performance of a floor/ceiling with the rating system called
the ‘Fire Resistance Level’ (FRL). The FRL rating of the
systems detailed in this guide are opinions issued by the
CSIRO based on test results.
Testing has been conducted in accordance with the
Australian Standard AS1530 : Part 4 ‘Fire Resistance Tests
of Elements of Building Construction’.
The FRL rating consists of three performance criteria,
structural adequacy/integrity/insulation. For example, the
FRL of a floor may be expressed as 180/120/90. Where
‘180’ indicates a rating for ‘structural adequacy’ of 180
minutes, followed by ‘integrity’ for 120 minutes, and
‘insulation’ for 90 minutes. The Hebel® PowerFloor™
system has fire resistance of 240 minutes from a fire
source above the floor. For fire resistance to a fire source
below the floor a fire rated ceiling system must be
installed.
14
Floor systems, consisting of the Hebel® PowerFloor™ and
other products, have been laboratory tested to establish
their sound insulation characteristics. A laboratory test
involves the installation of a system between two massive
concrete rooms, which are normally well isolated from one
another,
so that only direct transmission is via the system.
A steady sound level of various frequencies is generated
on one side and measurements taken on both sides. These
measurements are made in one/third octave bands from
100Hz to 5000Hz. For each specified frequency, the sound
transmission loss is calculated. To assist in communication
the performance is conveniently expressed as a single
number called the ‘Weighted Sound Reduction Index’ (Rw).
Weighted Sound Reduction Index (Rw)
Recently, Australian building regulations have adopted
the International Standard Organisation acoustic rating
system called the ‘Weighted Sound Reduction Index’ (Rw).
The Rw value replaces ‘Sound Transmission Class’ (STC)
as a measure of the acoustic performance of a wall. A
correction figure of Ctr is added to the Rw value to better
quantify the acoustic performance of the building system.
Ctr Adaptation Term
The normal rating of Rw more closely defines the acoustic
performance for speech frequencies. Where low frequency
sound insulation performance is important, as may be
the case with traffic noise or music and DVD systems,
then a correction factor is applied to the airborne sound
rating (Rw) to differentiate the systems with good sound
insulation to these frequencies. The factor is Ctr and it
is a negative value. A system with good low frequency
performance will have a value of say -4; a system with
poor performance will have a value of say -12.
Impact Isolation Class (IIC)
The ‘Impact Isolation Class’ (IIC) quantifies the transmission
of impact sound through a floor/ceiling system.
The test involves impacting the floor assembly with a
standard tapping machine and measuring the sound level
below in the same manner as described for the airborne
sound insulation. Higher numbers indicate less sound is
being transmitted. IIC is an American system and is now
being replaced by Ln,w, which is the ISO equivalent.
This is the measure of the weighted and adjusted
sound level below the floor when the tapping machine
is operated above. In this case the lower the value the
better the acoustic performance.
Thermal Performance
There is an approximate relationship between Ln,w
and IIC, either can be subtracted from the numerical
value of 110 to determine the other.
Thermal performance is concerned with the energy
retention or loss characteristics of a building system.
One of the primary design objectives in planning a cost
effective building is to provide a comfortable living/
working environment for the building’s inhabitants.
Exploiting the inherent thermal qualities of Hebel® AAC
enables the designer to achieve this objective.
C1 Adaptation Term
R-Value Rating
The rating by Ln,w appears to work well where carpets
or floating floors are employed on concrete or timber
framed floors. With hard floor finishes, particularly with
timber joist floors, the low frequency performance may
require further consideration by your acoustic consultant.
The energy demand can be minimised by controlling
the heat transfer, which is heat flowing from a hot
region to a colder region, through a building system.
The thermal resistance of a building system is
expressed as the R-Value. The R-Value of the system is
the sum of the R-Values of the individual components.
Test Reports
All test reports quoted in this guide have been issued
by the CSIRO, National Acoustic Laboratory or other
NATA Registered Laboratories. Testing has been
conducted in accordance with the relevant Australian
Standard at the time of testing.
Sound Transmission Estimates
Computer models are used to determine sound
transmission estimates for specific configurations, known
as ‘Acoustic Assessments’. The computer model predicts
the Rw performance expected from the laboratory test
on the system, with a 96% confidence limit of ±2.5 db.
System performance
Ln,w
Thermal Integrity
Poor thermal integrity, due to bad construction
practices can also significantly affect the comfort
performance, as poor sealing and gaps allow air to
infiltrate as drafts. The inherent construction tolerances
of Hebel® PowerFloor™ provides a floor with a low
infiltration rate and good thermal integrity.
Performance – Laboratory vs Field.
When selecting the appropriate TECSLAB™ system, the
designer or specifier must be aware that the laboratory
Rw values are always higher than the field measured
values (Rw). This is due to the field conditions, such as
flanking paths, air leaks, floor frame construction type
and stiffness, etc., which can be introduced by careless
building design or construction. To avoid significant
reductions in acoustic performance published
construction details must be followed completely.
Independent specific advice and confirmation should
be sought for specific projects where the presence of
flanking paths or any other acoustic effect may affect
field performance.
Typically, the field performance of a system will be 2
to 5 Rw units lower than the laboratory performance,
and allowance should be made for this by the acoustic
consultant during the selection of the floor system.

2.2 Building Regulations
Intertenancy Floors
Floors constructed between separate tenancies are
required to achieve a minimum acoustic and fire
performance.
Acoustic Performance
For Class 2 and 3 Building with floors separating sole
occupancies the following minimum acoustic requirements
are described in the BCA:
• Airborne Sound Transmission:
Rw + Ctr ≥ 50
•Impact Sound Transmission:
Ln,w + Cl ≤ 62
Or, measured in-situ performance of:
• Airborne Sound Transmission:
Dnt,w + Ctr ≥ 50
•Impact Sound Transmission:
Lnt,w + CI ≤ 62
Fire Performance
For Class 2 and 3 Building with floors separating sole
occupancies the following fire requirements are described
in the BCA:
•FRL - 90/90/90 (Structural Adequacy/ Integrity/
Insulation)
Please refer to section C of the BCA for certain exemptions
to the above fire rating requirements.
16
Compliance with the Building Code of Australia
(BCA)
All building solutions, such as walls, floors, ceilings, etc.
must comply with the regulations outlined in the BCA or
other authority.
The BCA is a performance based document, and is
available in two volumes which align with two groups
of ‘Class of Building’:
Volume 1: Class 2 to Class 9 Buildings; and
Volume 2: Class 1 & Class 10 Buildings – Housing
Provisions.
Each volume presents regulatory Performance
Requirements for different Building Solutions for various
classes of buildings and performance provisions.
These Performance Provisions include: Structure; Fire
Resistance; Damp & Weatherproofing; Sound Transmission
& Insulation; and Energy Efficiency.
This design guide presents tables, charts and information
necessary to design a Hebel® PowerWall™ that complies
with the Performance Requirements of the BCA. The
designer must check the adequacy of the building solution
for Performance Requirements outlined by the appropriate
authority.

3.1 TECSLAB™ Installation Sequence
1.Preparation of Framing for Hebel®
PowerFloor™ Panel Installation
• Check floor framing is complete and within level tolerances.
• Provide set-out chalk lines, as required.
• Provide temporary installation platform where necessary.
• Ensure floor framing has adequate strength to support
Hebel® PowerFloor™ bundles.
• Position Hebel® PowerFloor™ bundles on the floor framing.
2.Hebel® PowerFloor™ Panel
Installation
• Panels are to be installed in a stretcher bond pattern, with a
minimum overlap of 1 joist space and not less than 450mm.
• Use lifting handles or trolley to move the panels to
installation area.
• Apply a 5mm min. bead of Fuller Max Bond construction
adhesive (or equivalent) to top of joists in accordance with
manufacturer’s instructions, and apply Hebel® Adhesive to
appropriate panel edges.
• Panels must be installed with minimal horizontal sliding
on the joists to ensure a good bond. Force the tongue
and groove joint closed as the panel is rolled and lowered
onto the joists. Ensure all joints are tight and that adhesive
makes full contact along all joints.
• Screw fix panel to the joists as required.
• Repeat process, removing excess Hebel® Adhesive.
3.Penetration Detailing
• Install blocking to support Hebel® PowerFloor™ panel at
major openings.
4.Floor Finishes
• Sweep the floor surface to remove debris and loose
particles.
• Fill joints and screw holes with Hebel® Adhesive, as
required.
• Ensure perimeter is not chipped.
•Install floor covering for Hebel® PowerFloor system in
accordance with manufacturer’s specifications.
Note: Ensure panel moisture content is within limits outlined by
the floor covering manufacturer.

3.11 Floor Covering Installation
Minimum medium duty underlay is to be used. No
other special requirements.
Panel Surface Preparation
Sweep the floor surface to remove debris and loose
particles. Expose all surface blemishes such as chips,
cracks, gaps, ridges or the like. Fill all unacceptable
locations with an appropriate and compatible patching
compound such as Hebel® Patch or levelling compound
as required. Ensure panels are then dry.
Carpet Smooth Edge Installation
As per carpet manufacturer’s guidelines. No other
special requirements.
Fig 3.40
Fig 3.41
Installation of Carpet Smooth Edge (Gripper) is to be in
accordance with AS/NZS 2455.1:1995.
Installation of carpet gripper prior to laying carpet
requires the use of specifically selected nails or
course threaded screws. Standard fixings supplied
with the carpet gripper are not suitable for fixing to
Hebel® PowerFloor™ panels. Carpet gripper strips
are available without factory supplied nails. For
carpet gripper installation near the panel edge, only
glue is recommended. If relying on glue only, the
carpet can not be stretched until the glue is set after
approximately 24 hours.

Sweep the floor surface to remove debris and loose
particles. Expose all surface blemishes such as chips,
cracks, gaps, ridges or the like. Fill all unacceptable
locations with an appropriate and compatible patching
compound such as Hebel® Patch or levelling compound
as required. Ensure panels are then dry.
Batten fix – ensuring flatness is not as critical as direct
mechanical fix. Anchor battens at the required centres
using anchors suitable for AAC, eg. Mungo MBSP1080.
Direct mechanical fix – install min. 12mm plywood
sheets to Hebel® PowerFloor™ using construction
Maxbond or equivalent and 65-75mm coarse thread
countersunk screws at max 600mm centres.
Moisture
Timber is affected by changes in environmental
conditions and it is good practice to allow the flooring
to acclimatise to the environment before installation.
If there is significant moisture in the Hebel®
PowerFloor™ (>6%) a membrane, such as min. 200
micron polyethylene sheeting, should be placed over
the top surface of the Hebel® PowerFloor™.

4.1 Delivery and Storage
Unloading Panel Packs
If outside, Hebel® panels must be stored off the ground
and protected from the weather. Only single bundles
positioned on the ground can be opened. To provide a
level surface, we recommend placing temporary joists
beneath the supporting cleats.
Panel packs shall be unloaded and moved with only
approved lifting devices. Before use, the lifting devices
should be checked for the required lifting tags. Packs
should be unloaded as close as possible to the intended
installation area. This will increase work efficiency and
minimise the need for secondary lifting.
Unstrapping Packs
Ensure appropriate bracing is installed to packs prior to
removal of strapping to prevent panels from falling. Panels
can be held together with sash clamps, ratchet, straps or
Hebel® stabilising bars.
Note: Secondary handling increases the risk of panel damage.
The repair of damage sustained during lifting and moving
is the responsibility of the lifter. Where damage is excessive,
PowerClad panels must be replaced.
Storage
Refer to TECBEAM™ Installation Guidelines for delivery and
storage of TECBEAM™s.
All materials must be kept dry and preferably stored
undercover. Care should be taken to avoid sagging or
damage to ends, edges and surfaces.
All Hebel® products must be stacked on edge and properly
supported off the ground, on a level platform. Panel
bundles can be stacked two high. The project engineer
should be consulted as to the adequacy of the structure to
support the stacked bundles.

saw fitted with a diamond tipped blade. The use of power
tools may cause dust, which contains respirable crystalline
silica, with the potential to cause bronchitis, silicosis and
lung cancer after repeated and prolonged exposure. When
using power or hand tools on Hebel® products, wear a
P1 or P2 respirator and eye protection. When cutting,
routing or chasing Hebel® products with power tools, use
dust extraction equipment and wear hearing protection.
Refer to CSR Hebel® MSDS sheets. For further information,
contact CSR Hebel® or visit our website:

Mortars & Adhesives
The Hebel® bagged mortar and adhesive should
be prepared in accordance with instructions on the
packaging.
Damaged Panels
Chipped or damaged panels are to be repaired using
Hebel® Patching Mortar. Your Hebel® supplier should be
notified immediately of any panel damage or cracking that
occurs during the handling of the panels. This damage may
result in the panel being structurally inadequate, in which
case it must be replaced.
36
Reinforcement exposed during cutting is to be coated with
a liberal application of Hebel® anti-corrosion protection
paint.
Manual Handling
CSR Hebel® recommends using a trolley or other
mechanical apparatus to move the panels around the
work site. Manual handling, where people physically
move a panel, should be kept to a minimum, with the
weight being supported by an individual kept as small
as possible. Any concerns
regarding the weight to be handled should be
discussed with the panel installing contractor.
To minimise the possibility of manual handling injuries,
CSR Hebel® suggests the following:
•
Use mechanical aids, such as trolleys, fork lifts,
cranes and levers, or team lifting to move panels.
•
Handling, storage and responsibility
4.4 Panel Handling
Keep the work place clean to reduce the risk of
slips, trips and falls which can cause injury.
• P
lan the sequence of installation to minimise panel
movements and avoid awkward lifts.
•
Keep the panels dry.
•
Train employees in good lifting techniques to
minimise the risk of injury.
Hebel® products are cement-based, which may irritate
the skin, resulting in itching and occasionally a red
rash. The wearing of gloves and suitable clothing
to reduce abrasion and irritation of the skin is
recommended when handling Hebel® products.

Following is a guide to assist in working out quantities
and costs for the required components of the Hebel®
PowerFloor™ system.
Please consult a licensed fabricator for a quote on
TECBEAMs™ for your project.
Step 1: Calculation of the Total
Floor Area
First calculate the total floor area of the building,
allowing for the panels to extend UNDER the external
wall frames.
The easiest way for this to be calculated is to determine
the overall wall length of the area being calculated,
then minus the exterior wall material and cavity
thickness. Below is a diagram of a house using the
Hebel® Low Rise External Wall System. This system gives
an overall exterior wall thickness of 185mm (90mm
stud frame, 20mm tophat batten and 75mm thick
Hebel® PowerPanel), so given the plan dimensions the
area would be worked out as follows:
• 14.000 - 0.095 - 0.095 = 13.810 m (0.095 = 75
mm Hebel® PowerPanel and 20 mm tophat)
•7.000 - 0.095 - 0.095 = 6.810 m
•Total Floor Area (TFA) = 13.810 x 6.810 = 94.0461
m2 (total area to the outside of the stud frame)
Step 2: Panel Waste
This can be calculated in two ways:
An accurate calculation by completing a detailed panel
layout and measuring the amount of waste that will
Appendix
Appendix B: Estimating TECSLAB™
be generated due to the layout of the house. Or By
applying a waste percentage to the Total Floor Area.
Generally allow an additional 5% of area. Therefore
multiply the Total Floor Area by 1.05. This calculation
gives you the total Adjusted Floor Area (TAFA).
Step 3: Material Quantities
Now that the floor area has been worked out we can
move on to working out the material quantities.
(A) Hebel® PowerFloor™ Panels:
• Area of one panel = (1.8m x 0.6m) = 1.08m2
• No. of panels = Total Adjusted Floor Area (TAFA) ÷
1.08m2
(B) Screws
•Joists @ 450cts = 8 screws required per m2 of floor
• Joists @ 600cts = 6 screws required per m2 of floor
• Total screws = (6 or 8) x Total Floor Area (TFA)
Note: Packs come in 2 sizes, 100 or 250.
Screws to be estimated based on the pack sizes.
(C) Hebel® Adhesive
• Each 20kg bag of Hebel® Adhesive glues 20m2 of
floor area.
• Total bags = Total Floor Area (TFA) ÷ 20
(D) Construction Adhesive
• Each tube of construction adhesive glues approx. 10
panels to the sub floor joists. This is 10 x 1.08m2 =
10.8m2 of floor area.
• Total tubes of adhesive = Total Floor Area (TFA) ÷
